Re: Limiting propogation of a route to a specific area

Curtis,
   You can put a *in-bound* distribute list in the router configuration section
 to deny the undesirable route. The unwanted route would still appear in the L
ink-State database, but wouldn't be placed into the routing table....

   Of course, the bad part about this is that you have to do this on all of the
 routers that don't want to see your route, since the LSAs don't get filtered.

   Any other ways anybody can think of?
